Lanthanum Oxide Powder

Product Description
Lanthanum oxide is a white amorphous powder. The density of 6.51g/cm3. The melting point of 2217 DEG C. Boiling point is 4200 ºC. Slightly soluble in water, soluble in acid and generates the corresponding salts. Exposed to air is easy to absorb carbon dioxide and water, gradually become lanthanum carbonate. Burning lanthanum oxide hydrate release a lot of heat.
The main application areas for the manufacture of special alloy precision optical glass with high refractive index, optical fiber board, suitable for the camera, camera, microscope lens and senior optical prisms. Also used in the manufacture of ceramic capacitor, piezoelectric ceramic doping agent and X ray luminescence materials with lanthanum oxide powder. Cerium lanthanum phosphorus ore by extraction or by burning or lanthanum nitrate and lanthanum carbonate. Can also be made by lanthanum oxalate heating decomposition can be prepared. Used as catalysts for many reactions, such as doped cadmium oxide catalytic carbon monoxide oxidation reaction, doped palladium catalytic hydrogenation of carbon monoxide to generate methane reaction. Leach into the lithium oxide or zirconium oxide lanthanum oxide ( 1% ) can be used for manufacturing ferrite magnet. Oxidative coupling of methane generation is ethane and ethylene very effective selective catalyst. For the improvement of barium titanate, strontium titanate ( BaTiO3 ) ( SrTiO3 ) of the temperature dependence of ferroelectric and dielectric properties, as well as the manufacture of fiber optics and optical glass.
